' Application tied Iuiy 14,1898. serial No. 685,946. ou man.)

nation and arrangement of parts hereinafter more fully described,illustrated in the accompanying drawings,and particularly pointed out inthe claim.

In the drawings, Figure l1 is a perspective View showing the elongatedpiece of spring metal in position. Fig. 2 is across-sectional viewthereof, showing the locking means.

Fig. 3 is a perspective view of the elongated` piece of spring metal.Fig. 4 is a disassembled view of the locking means.

Referring to the drawings, in which like numerals of reference indicatecorresponding parts throughout the several views, 1 indicates thewindow-,frame of the ordinary construction,having the usual verticalextensions 2, 3, and 4 suitably secured thereto, forming between themthe inclosing or sliding spaces 5 and 6 for the window-sash.

Secured in the spaces 5 ando, at one side,

as at 8, is an elongated piece of spring metal 9. This piece of metal iscurved, as shown, and is adapted to operate against the inner edge ofthe sash. The inner edge of the sash is rabbeted, forming the space 10and the rib or flange 11. The rabbeted portion of th sash is inclined,as shown at 12.

The sash 7 has a slot formed therein, this slot being of greaterdiameter at its inner l edge, as at 13, than at its outer end, as at14..

Operating in the said slot is a locking-pin 15, having a suitablehead16. This locking-pin is actuated by the coil-spring 17, which surroundsthe same and is arranged Within the enlarged portion of the slot betweenthe pin 18, extending transversely through the pin 15, and the inner endof said enlarged portion of the slot.

The metal strip has apertures 19 formed therein a suitable distanceapart for the operation therein of the end of the locking-pin.

2O are apertures formed in the metal strip for the purpose of securingthe same to the sash by means of the screws 21.

The spring-metal strip while serving to form a part of the lock alsoincidentally acts as aweather-strip and permits the dispensing with ofthe ordinary weather-strip 0r partingbead.

It is thought that no further explanation is necessary, owing to thesimplicity of my device.-

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.l

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

A window-sash lock consisting of a springmetal strip having its one edgecurved outwardly and its other edge secured within thel recess ofthewindow-frame, said strip being provided'throughout its secured edgewith a `series of apertures, combined with a windowsash rail having arabbet to receive the projecting edgeof said spring-strip, said sashrailbeing further provided with a recess andV an opening registeringtherewith, a lockingpin arranged in saidy recess and operating throughsaid opening and adapted to engage in the apertures of the spring-metalstrip to lock the sash, a stop-pin secured in said locking-pin, and acoil-spring arranged upon said locking-pin between thestop-pin and theinner end of the recess in the sash-rail for holding said locking-pin inlocking engagement with the metal strip, substantially as set forth. Intestimony whereof I affix my signature in the presence of twowitnesses.
